Note: The sum of all the bytes in the message is 173 (hex). Checksums are
transmitted in a sixteen bit format. The value 01 (hex) is equivalent to the
ASCII control code SOH, 49 (hex) is equivalent to the ASCII character I,
and 73 (hex) is equivalent to the ASCII character “s” (refer to Appendix C).
